 suBaeTCH sie>K^.y nponiiMi Harmer (05) The view that 

 the pericardium is the fellow to the anterior body-cavity 



has been suggested for Balanoglossus by Bouj-ne and 

 Spengel, but it may be remarked that the strictly me- 

 dian position of the pericardium in the later stages of 

 Cephalodiscus and the fact that both proboscis-pores 

 open iuto the anterior body-cavity are not in favour of 

 this view» (CTp. 97). ABTopi,, Men<Ay npo i insn., bckojh>3l
